Thanks all for the compliments. Tomorrow will be one week since we bought him.
So far - all is calm in his little 5 gallon world.
Today I topped the tank off with some treated tap water to make up for all the multiple daily water tests we've been doing and evaporation.
Tomorrow I will probably fast him.
He's been a good eater from the start....I use the NLS betta pellets and I have some frozen daphnia (that took some practice - but he LOVED it)...and some freeze dried bloodworms (I've not used them yet but will soak maybe one a week in tank water as a treat).

Hopefully all will continue to go well. My daughter picked him - and he's not the fish I'd have picked - but she did a great job because he's got a really fun personality about him. I think I'm enjoying him more than she is - hahaha....
Now...that 45 gallon tank we have...I could partition it and put HOW many Bettas in it??
